Appeal No. 2005-2695
Application No. 10/280,926
BACKGROUND
Appellants’ invention relates to a compact input/output signal driver for
electrostatic discharge protection. An understanding of the invention can be derived
from a reading of exemplary claims 7 and 19, which are reproduced below.
7. A method comprising:
forming an electrode over a substrate;
forming a lateral diode including said electrode and opposed regions of
opposite conductivity type in said substrate, said regions being opposed from
one another across said electrode;
forming a transistor using said electrode as the gate of said transistor; and
fabricating an input/output signal driver with electrostatic discharge
protection using said diode and transistor.
19. A method comprising:
forming a first C-shaped electrode;
using said first C-shaped electrode as a mask to form a lateral diode
having a pair of opposed regions across said electrode, said regions being of
opposite conductivity type;
using said first C-shaped electrode as a mask to form the source and
drain of a transistor, said electrode to act as a gate of said transistor; and
fabricating an input/output signal driver with electrostatic discharge
protection using said diode and transistor.
